System Beep Codes
When errors occur during the boot routine that cannot be
reported on the built-in display or on an external monitor
(if attached), the computer may emit a series of beeps that
identify the problem. The beep code is a pattern of
sounds: for example, one beep, followed by a second
beep, and then a burst of three beeps (code 1-1-3) means
that the computer was unable to read the data in non-
volatile random-access memory (NVRAM). This
information is important to the Dell support staff if you
need to call for technical assistance.

When a beep code is emitted, write it down on a copy of
the Diagnostics Checklist found in Chapter 5, and then
look it up in Table 3-3. If you are unable to resolve the
problem by looking up the meaning of the beep code, use
the Dell Diagnostics to identify a more serious cause.
(See Chapter 4, “Running the Dell Diagnostics.”) If you
are still unable to resolve the problem, call Dell for tech-
nical assistance. (See Chapter 5, “Getting Help,” for
instructions.)
